I have made a couple of visits to a local garden centre lately. It is an independent family run nursery that can always be guaranteed to have some quality plants. It's logo is a watering can with a giant one on the side of the road outside.
The entrance in the car park is equally novel.
With a great weather vane.
There are watering cans wherever you look including outside the loos.
Watering cans also make could plant containers.
I have an old one planted up in the garden. I promise you a photo soon.
